Filed st. 22, 1964, Ser. No. 405,809 4 Claims. (Ci. 3l223l) This invention relates to portable supply cases with a working surface combined therewith, the cases being of such a size as may be easily carried with the person and more particularly the invention relates to a student-giftcase for art and science, or a portable technical-study workshop screen case.

An object generally of the invention is the provision of a portable size, technical-study workshop screen case which will be practical and convenient to study, draw, write, type, paint, survey with, or to do any survey research in a practical way, and not too expensive for Industry to fabricate.

Another object of the invention is the provision of a study supply case comprising a body section with an open top, a reciprocally movable drawer mounted in sliding contact with the bottom wall of said body section and closing the open end thereof, a cover plate pivotally connected at its front end to the front end of the body section whereby it can swing from closed position to open position, and having means to secure the cover and the drawer with the body section when the drawer is in closed position.

A further object of the invention is the provision of a case with a novel fastening means connecting the drawer with the cover whereby the cover plate is locked by a drawer attachment when the drawer is in nonoperative position and is unlocked when the drawer is moved to its outer operative position.

A still further object of the invention is to provide a student case which will be convenient for every student in grade school, high school and college, as well as professors, scientists, artists, engineers, business executives, diplomats, surveyors, explorers and other research work ers.

A still further object of the invention is the provision of a convenient, technical, practical device for studying in comfort, and which adjusts very conveniently, quickly to proper position as desired; each operator will do better work when in proper position and capable of adjusting the same for light visibility so as not to strain the eye sight.

A more particular object of the invention is the provision of means, or a portable technical-study workshop screen case which can be carried under the arm, or by hand as books, or it can be enclosed in a brief case in gen eral travel on land, sea or air, or in space by astronauts. The working screen being adjustable to any desired or required position; the screen serving as the top cover of the equipment case when in non-elevated position.

Another object of the invention is to provide a case with two small leather loops of belt to strap the case upon the workers knee, keeping it firmly in position when in use by the operator in flight.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end our invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

Referring more particularly to the drawings, the invention is illustrated as embodied in a supply case and screen taking the form of a main rectangular container 15 consisting of a body section 16, a reciprocally movable supply drawer l7, and a cover plate member 18. The body section having a bottom plate 25, two side walls 19 and 20, a rear end Wall 21, a longitudinal slot 22 in each side wall, and an inverted L shaped latch member '23 attached to the rear wall 21. The cover 18 consists of a screen working surface 26 attached to longitudinal side supporting members 27. The forward ends of said supports 27 are pivotally secured to the forward ends of said side walls 19 and Zll by rivets 28. Two cover member supporting links 29 are provided, the upper ends of said links 2% are pivotally secured to the cover side supports 27 intermediate .the ends thereof by rivets The lower ends of said links 29 are provided with a bore through which a bolt 31 extends, said bolts 31 have a threaded stem 32 and a semi-cylindrically shaped head 33 with a fiat edge portion 34. A locking nut 35 having a threaded bore 36 and handle portion 37 is assembled upon said stem 32; see FIGURES 1 and 6. The stems 32 of the bolts are assembled through the bores in each link 22?, then through the slots 22 extending to the exterior of the side walls 19 and 20, after which the locking nut is assembled to the stems 32 and turned into locking engagement with the side walls 19 and 20 in juxtaposition with said slots 22. The bolts 31 may be moved rearwardly and forwardly in the slots 22, rearward movement of the bolts will pull upon the links 29 and lower the cover 18 while forward movement of the links 2-9 will push the links 29 upwardly causing the rear end portion of the cover 18 to travel upwardly in an arc since the forward end of the cover 18 is pivotally secured to the side walls 19 and 20. The drawer 17 consists of a bottom wall 40, an end wall 41, two side walls 42 and 43, a front wall 44, and a locking hasp 45 rigidly secured to the rear side of the end wall 41 and extending rearw-ardly therefrom to pass over the latch 23 attached to rear wall 21 and cooperate therewith when the drawer is in closed position; at which time the vertical bore 46 is in vertical alignment with the vertical bore 47 in latch 23 adaptable to receive a locking pin 48 assembled with the rear end portion of cover 18; see FIG- URE 1. As shown by FIGURE 8, the locking pin has a a stem 4-9 thread at its free end and free of threads at its upper end. A nut 50 is rigidly assembled between the upper and lower surfaces of the screen working member 26. The stem 49 has a handle member 52 integrally assembled therewith whereby the stem can be rotated and screwed into the bore 47 of latch 23 when the cover 18 is in its lowermost position, thus locking the hasp between said latch 23 and the working member 26 of the cover 18. The stem 48 also extends through a. bore 53 provided midway between the ends of a ruler 54 arranged upon the top surface of the cover 18 and at the rear end thereof. Turning the handle 52 clockwise within the nut will tighten the ruler against the top surface of the cover 18; the ruler 54 forming a card holder, a paper holder, a map holder, or a holder for any sheet material inserted between it and the top surface of the cover 18. The ruler 54 may be completely removed should its use be required at a remote place, later to be re-assembled with the cover. A stop-block means 55 is rigidly assembled to the forward ends of the side supports 27 of the cover permitting a limited reciprocal movement of the drawer 17, preventing the drawer from accidental removal from the body section 16. The front wall 44 of drawer 17 is provided with a transversely arranged handle 57 for operating the drawer movement within the body section 16. The side walls 42 and 43 of the drawer are provided with open portions 53 and 59 due to the fact the said side walls do not extend the entire length of the drawer, the openings supply means whereby a long ruler or the like may be placed transversely on the bottom wall 40 while in use, and also provides an easy manner to examine the contents of the drawer.

While in use, the container 15, or case, can be placed upon the lap of the user while in a seated position, the cover may be raised to the desired angle for working and locked in the elevated position. Two leather straps 60 and 61 are provided, one end of each strap is pivotally secured to one of the rivets 28 which extend through the side walls 19, 20 and side supports 27. Said strap 60 is provided with holes 62 longitudinally spaced to cooperate with a buckle 63. The second strap has a buckle 63 secured to the free end thereof. The free ends of the straps 6t and 61 can be placed under the users legs and buckled together to fasten the case upon the lap of the user.

As shown by FIGURES 9 and 10, the drawer 17 has an angle plate 65 secured to the rear wall surface of rear end wall 41, the horizontal extension 66 extending rearwardly therefrom and in horizontal alignment with the top edge of the drawer. The rear end portion of the cover 18 is provided with a channel member 67 arranged transversely on its side with its opening extending forwardly. The top side wall 68 of said channel member 67 is riveted to the lower surface of the screen plate 26 whereby the lower side wall 69 is arranged beneath the said wall 68. In use, when the drawer is moved to its rear most location the angle plate extension 66 will penetrate the opening between the side walls 68 and 69, the extension 66 will lock the cover 18 in a horizontal position and in contact with said container when it is in a horizontal position. The drawer 17 is prevented from being elevated by a plurality of pins 72 assembled to the inside vertical side walls of the body section adjacent the rear ends thereof, and adjacent the upper longitudinal edge thereof.

As clearly shown by FIGURES 1, 2 and 4, the body section is provided with tubular members 70 and 71, said members secured to the bottom plate 25 and adjacent the side walls 19 and 20. The drawer 17 is of a width equal to the distance between said tubular members 70 and 71, thereby providing a space between each of the side walls 42 and 43 and the side walls 19 and 20. The said spaces between the wall of the drawer and those of the body section are required to enable the links 29 to move therein as well as providing space for the head 33 on bolt 31 to travel adjacent the slots 22; all clearly shown by FIGURE 7. The diameter of the tubular members 70 and 71 will govern the size of the space between the walls of said drawer and the walls of said body section.

Thus it will be seen that we have provided in combination with a student case having means to carry supplies with the case closed, novel means for preventing opening of the cover and locking same in closed position.

Having thus described our invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of our invention; hence, we do not wish to be understood as limiting ourselves to the exact form, construction, arrangement, and combination of parts herein shown and described or uses mentioned.
